TO ALL WHOM IT'MAY OONCERN:

Be it known that I, ELIZUR H, BARNES, of Marathon, in the county ofCortland, and State of New York, have invented a new andy usefulImprovement in Apparatus to be used in Surgical Operations in ReducingFractures or Dislocations; and I`do hereby declare that the following isa full,.clear, and exact description of the sume, reference being hadtothe accompanying drawings, making apart'of this my specication.

The apparatus is composed of a number. of pieces, more or less of `whichwill be used, depending upon the part.of the body injured or operatedupon.' VThese pieces are shown in detail on the left and upper portionof 'the drawing.

Figure represents the entire apparatus as applied in actual use. Figure2, onlyv a. part ofthe apparatus as'applied to the lotver portion ot'Vthe leg; and Figure 3 shows the appliation of the parts required to thearni.

I is a rod, sa'y, fifteen inches in length, with a movable foot-piece,J, at its lower end, and at its upper'end the spur-Wheel G working in acase. A catch-spring, t, .operates upon the cogs to hold them at anydesired point. Through the casing of the wheel Gr, and along the side ofthe rod I, slides a cogged bar, F, worked up or' down by the spur-wheelG. E is a short piece of tubinglitting on to the end of the rod I. Intothe upper Yend of the tube is tted the curved. knee-piece K, ns in fig,2, and which can be used in front of either leg by reversing the endsfitting in the tube. This is bandaged or strapped to the' leg,'and thefoot-piece to theffoot.

The Wrench II is then applied tothe shal'tpi' the wheel G, and suchtension applied to the limb as the casc'xnay require, and this tensionis kept up until, by pressure. upon the springt, the spur-wheel is lei'tfree to move v beek, and thus lesson or remove the tension.

The sante pieces are applied in ig.-3 to the arm, with the exception vofthe rest-,0, which is substituted under the arm, for thetubing and thecurved piece K. This rest, C, is made nearly flat, so as to allow ofbringing the arm forward, or extending it directly from the side. A

'In case of fracture or dislocation of the thigh, iig. l, the bur or rodD, bent as represented at the upper end., is inserted in the upper endofthe tube E, to lengthenout the apparatus, and the form or rest, C, isapplied to the upper end, by irhich it niay be strapped to' the body.I-n case'tlie body becomes chafcdor sore,'or it becomes desirable fromo'tler causc,th e apparatus may be still further extended by another baror rod, B, with a rest, A, fitting upon tsnpper end, and under the arm,this last extehsionbei'ng governed by the ratchet on the vrod B, and thespring-catch S, in the ense upon Vthe upper part ot'V the rod D. Inenses'nhere it may be desirable to use a longer apparatus than is madeby the rods I and F, the rod D may be used in place ot F.

his apparatusis easily taken apart and put together, light and portable,andA being applied to the outer part of the limb or bo'dy, may be lcepton the patient, and theliinb kept in position as long as required.

I make n0 claim to the parts of this apparatus designated by thc lettersI, Gr, and F, separately or in combination with each other; but

I do elaine, and desire to secure by Letters Patent- 1. Thecurved formsor rests K and C, when used, respectively, upon the leg or arm, incombination with theparts I, F, and G.

2. The rod D, \'vhen bent as represented at its upper end, incombination with the said parts, I, F, and G, for vthe purposes setforth.

3. The rod B and rest A, in combination with the parts'D, I, F, and L,for the uses and purposes set forth.

E. H. BARNES.
